Description

Technical Field

[0001] The utility model relates to the technical field of corridor construction devices, in particular to an anti-falling device for the construction of aerial steel structure corridors. Background Art

[0002] Steel structure is a structure made of steel materials. It is one of the main types of building structures. It is mainly composed of steel beams, steel columns, steel trusses and other components made of steel and steel plates, and is treated with rust removal and anti-rust processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, sky corridors and other fields.

[0003] In the patent document with publication number CN214786204U, a fall prevention protection device for the construction of an aerial steel structure corridor is disclosed. The device is provided with a lower baffle, an upper baffle and a first gear. The control panel controls the corresponding rotating motor to rotate, driving the lower baffle inside the same installation frame to move relative to each other to avoid collision between the lower baffle and the floor slab. At the same time, the corresponding rotating motor is controlled to rotate, driving the upper baffle inside the installation frame at the top of the steel structure corridor to move toward each other, so that the upper baffle protrudes out of the installation frame. When the steel structure corridor accidentally falls, the upper baffle will fall onto the floor slab. At this time, the floor slab can support the steel structure corridor through the upper baffle. When the upper baffle moves upward and contacts the steel structure corridor, the control panel controls the external traction mechanism to suspend traction and controls the corresponding The corresponding rotating motor runs to retract the upper baffle into the installation frame, and at the same time, the lower baffle protrudes from the two ends of the installation frame at the bottom of the steel structure corridor. At this time, the control panel controls the external traction mechanism to pull the steel structure corridor upward by a distance of the same thickness as the lower baffle and the upper baffle. Then the control panel controls the external traction mechanism to stop traction, and at the same time controls the corresponding rotating motor to run to retract the lower baffle into the installation frame, and at the same time, the upper baffle protrudes from the two ends of the installation frame at the top of the steel structure corridor. Repeating the above steps can allow the lower baffle and the upper baffle to move upward with the steel structure corridor while ensuring that the steel structure corridor will not fall. At the same time, when the steel structure corridor falls, the distance between the lower baffle and the upper baffle and the floor will not be too large to prevent the lower baffle and the upper baffle from damaging the floor when falling.

[0004] During the construction of the aerial steel structure corridor, safety protection measures need to be taken, so anti-fall protection devices are needed. However, the existing anti-fall protection devices have the following problems:

[0005] 1. The installation of existing fall protection devices is laborious and time-consuming;

[0006] 2. The existing anti-fall protection device is very inconvenient to dismantle at a later stage, and the dismantling is dangerous.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1 - Figure 5 The utility model provides a technical solution: an anti-falling device for the construction of an aerial steel structure corridor, comprising a mobile vehicle 101 and a telescopic reinforcement column 102, wherein the telescopic reinforcement column 102 is installed on the top of the mobile vehicle 101, and an anti-falling device is installed on the top of the mobile vehicle 101, wherein the anti-falling device comprises a telescopic unit and a reinforcement unit, and both the telescopic unit and the reinforcement unit are installed on the top of the mobile vehicle 101;

[0029] The telescopic unit includes a motor 201, a threaded rod 202, a movable nut 203, a connecting shaft 1 204, a connecting rod 205, a connecting shaft 206, a T-shaped fixing block 207, and a telescopic plate 208. The top plate 103 is installed on the top of the telescopic reinforcement column 102. The motor 201 is installed inside the mobile vehicle 101, the threaded rod 202 is installed on the output shaft of the motor 201, the movable nut 203 is installed on the outer surface of the threaded rod 202, the connecting shaft 1 204 is opened inside the movable nut 203, the connecting rod 205 is installed on the outer surface of the connecting shaft 1 204, and the connecting shaft 206 is installed. At the other end of the connecting shaft 1 204, the telescopic plate 208 is installed inside the top plate 103, and the T-shaped fixing block 207 is installed at the bottom of the connecting shaft 206. The T-shaped fixing block 207 is movably connected to the connecting shaft 206. By installing the telescopic unit, after the device is positioned, the motor 201 is started to drive the threaded rod 202 to rotate, so that the movable nut 203 moves up and down on the outer surface of the threaded rod 202. Since the connecting rod 205 is a fixed length, the telescopic plate 208 begins to extend to both sides, thereby increasing the working range of the device.

[0030] A threaded hole is provided inside the movable nut 203 , and the threaded hole and the threaded rod 202 are adapted to each other, so that when the threaded rod 202 rotates, it engages with the threaded hole inside the movable nut 203 , so that the movable nut 203 moves up and down on the outer surface of the threaded rod 202 .

[0031] The shape of the threaded rod 202 is smooth on both the top and bottom, and a rotating rod with a thread line is opened in the middle, so that the bottom of the threaded rod 202 is smoothly connected to the bevel gear 301 for transmission.

[0032] The reinforcement unit includes a bevel gear 1 301, a bevel gear 2 302, a fixed plate 303, a rotating shaft 304, a transmission assembly 305, a rotating shaft 306, a winding drum 307, a fixed steel wire 308, and a connecting buckle 309. The bevel gear 1 301 is installed at the smooth bottom of the outer surface of the threaded rod 202, the bevel gear 2 302 is meshed with the side of the bevel gear 1 301, the rotating shaft 304 is installed inside the bevel gear 2 302, the fixed plate 303 is installed on the outer surface of the rotating shaft 304, the transmission assembly 305 is installed on the outer surface of the rotating shaft 304, the rotating shaft 306 is installed inside the transmission assembly 305, and the winding drum 307 is installed on the rotating shaft 306. The outer surface, the fixed steel wire 308 is wound around the outer surface of the winding drum 307, and the connecting buckle 309 is installed on the top of the telescopic plate 208. By installing the reinforcement unit, when the motor 201 drives the threaded rod 202 to rotate, it drives the bevel gear 1 301 and the bevel gear 2 302 to engage, thereby further controlling the transmission assembly 305 to work through the rotating shaft 304, so that the fixed steel wire 308 on the outer surface of the winding drum 307 cooperates with the telescopic plate 208 to telescope, and the two ends of the fixed steel wire 308 are respectively wound around the outer surface of the winding drum 307 in opposite directions, thereby providing top reinforcement support for the telescopic plate 208, and further improving the stability of the device.

[0033] The fixing wire 308 has two ends, which are fixedly connected to the connecting buckles 309 on both sides respectively.

[0034] A hydraulic rod 104 is installed at the lower part of the interior of the mobile vehicle 101, and a buffer spring 105 is installed on the outer surface of the hydraulic rod 104. An anti-skid pad 106 is installed at the bottom of the hydraulic rod 104. By arranging the hydraulic rod 104 at the bottom, when the device reaches a predetermined position, the hydraulic rod 104 is started to lift the entire top of the device, so that the bottom tires of the mobile vehicle 101 do not contact the ground, thereby fixing the bottom of the device. At the same time, by installing the anti-skid pad 106, the friction between the ground is increased, making the device more firmly fixed.

[0035] A recovery groove for recovering the connecting buckle 309 is provided at the top of the top plate 103, and a moving groove for moving the T-shaped fixing block 207 is provided at the bottom of the top plate 103. By providing the recovery groove and the moving groove, the device can provide limiting functions for the connecting buckle 309 and the T-shaped fixing block 207 respectively during the process of extending and retracting the telescopic plate 208.

[0036] There are four telescopic reinforcement columns 102 , which are respectively installed around the bottom of the top plate 103 . The four groups of telescopic reinforcement columns 102 provide support for the top plate 103 , so that the top plate 103 can be made more stable.

[0037] Working principle: After the mobile vehicle 101 is started and the device is driven by the mobile vehicle 101 to reach the specified position, the hydraulic rod 104 is started and the hydraulic rod 104 drives the entire device to move, so that the tire at the bottom of the mobile vehicle 101 does not contact the ground, and at the same time, the motor 201 is started and the motor 201 drives the threaded rod 202 to rotate. The threaded rod 202 rotates and the moving nut 203 moves up and down on the outer surface of the threaded rod 202, so that the threaded rod 202 drives the connecting rod 205 to start pushing the telescopic plate 208 outward, so that the telescopic plate 208 is moved from the inside of the top plate 103. The bevel gear 301 is extended and rotated by the threaded rod 202 at the same time, so that the bevel gear 1 301 and the bevel gear 2 302 are meshed with each other, so that the rotating shaft 304 inside the bevel gear 2 302 is rotated, so that the rotating shaft 304 drives the transmission component 305 to rotate (the transmission component 305 is composed of a transmission wheel, a transmission belt, and a driven wheel, wherein the transmission wheel is fixedly connected to the rotating shaft 304, and the driven wheel is fixedly connected to the rotating shaft 306), so that the rotating shaft 306 is rotated, and further drives the winding drum 307 to rotate, so that the fixed steel wire 308 begins to extend, thereby reinforcing the telescopic plate 208.
